Abstract

A format of an Infrared (IR) transmission from an IR remote is matched to a corresponding IR protocol format for a starting sequence associated with the transmission. Next, a format of a payload that follows the starting sequence in the transmission is matched to a payload format associated with the matched protocol format. Assuming both the starting sequence and the payload formats match, the transmission is relayed and/or replayed over an IR re-transmitter situated in proximity to an IR-enabled device associated with the IR remote, and the IR-enabled device processes a command represented in the payload of the transmission. When either the starting sequence fails to match a supported IR protocol or the payload format fails to match a given supported IR protocol, the transmission is ignored and discarded as unverified.

Description

BACKGROUND

Infrared (IR) communication is ubiquitous in the world of television device control. A popular means to control devices with universal remotes involves the use of the signal record and replay technique. This technique is not concerned with the underlying protocol but rather the storage and retransmission of a collection of signal samples. It is simple and effective but has a number of shortcomings.

The record and replay technique of providing IR device control suffers from two significant shortcomings. The first is its inability to programmatically detect signal errors. When an IR packet is recorded with a universal remote its validity must be manually verified by the individual through playback and observation. The second issue is scalability. The process of recording and storing device functions must be performed for each device and each function. This results in the storage of large collections of device and function sample sets.

SUMMARY

In various embodiments, methods and a device for infrared (IR) transmission verification and relay are presented.

According to an embodiment, a method for IR transmission verification and relay is presented. Starting signals in a wireless transmission are matched to a protocol. A payload format for the protocol is obtained and remaining signals in the wireless transmission are verified against the payload format. Finally, a determination is made as to whether to relay or to ignore the wireless transmission based on the verification of the payload format.

DETAILED DESCRIPTION

FIG. 1A is a diagram of a system 100 for IR transmission verification and relay, according to an example embodiment. It is to be noted that the components are shown schematically in greatly simplified form, with only those components relevant to understanding of the embodiments being illustrated.

Furthermore, the various components (that are identified in the FIG. 1) are illustrated and the arrangement of the components is presented for purposes of illustration only. It is to be noted that other arrangements with more or less components are possible without departing from the teachings of IR transmission verification and relay, presented herein and below.

The system 100 includes verify relay device 100 that includes a plurality of IR re-transmitters 111-112, an IR transmitter 113, a verifier 114, and an IR receiver 115. The system 100 also includes a plurality of IR remotes 120-130 that control a plurality of devices 121-122 via IR transmissions of signaling sent from the IR remotes 120-130.

The verify relay device 110 includes a processor, memory, and a non-transitory computer-readable storage medium. The verifier 114 is implemented as executable instructions that reside in the non-transitory computer-readable storage medium. The processor loads the executable instructions from the non-transitory computer-readable storage medium into memory and executes the executable instructions to perform the processing that is discussed herein and below for the verifier 114.

Unfortunately, there is a wide array of IR protocols that are used in the industry with little standardization. A conventional IR relay device merely records transmissions detected and then broadcasts the transmissions over all of the IR transmitters associated with the relay device. IR transmitters are needed in retail settings where a large number of IR-controlled devices are used, such as a television department in a retail store, a sports bar, a hotel, a restaurant, a shopping mall, and others. IR provides wireless signals below the visible spectrum at approximately 950 nm or lower with frequencies between 30 kHz to 60 kHz. As a result, conventional IR remotes need to be in close physical proximity to the IR devices for the devices to detect the signals. In settings where a large number of IR devices are being controlled via a universal remote or via individual remotes use of an IR relay device is necessary; however, conventional IR relay devices cannot verify the IR transmissions for purposes of selecting the appropriate IR transmitter that relays the IR transmission to the appropriate IR device. As a result, the IR relay device simply broadcasts over all its IR transmitters, this can cause some IR devices to respond unexpectedly by processing commands that were not directed to those IR devices, which can cause a great deal of confusion and frustration.

The system 100 and techniques herein provide the verify relay device 110 for verifying IR signaling and selectively relaying only verified IR transmissions over the appropriate and intended

IR re-transmitters

111 or 112 via the verifier 114 by re-playing the transmissions through the IR transmitter 113. This allows for customized and accurate control of a plurality of IR-controlled devices 121-122.

Each device manufacturer utilizes its own and sometimes proprietary protocol specification. Each command produced from a remote 120-130 modulates signals in different defined patterns for purposes of identifying one of its devices and issuing a command for the devices 121-122 to process. Some specifications are based on the duration of the signaling; other specifications are based on a length of the signaling (which still may involve some duration of time). All protocol specifications include a start sequence for their transmissions followed by a payload. Some follow the payload with an ending signal sequence. Some payloads include a specific device address/identifier before the command. Some alternate the ending signal sequence from payload to payload signal transmissions. At least a portion of the payload includes an IR command that is being directed to an IR device for processing.

The transition between a high then low transmission and a low then high transmission in an IR signal transmission is considered to be a “mark.” Following a mark where there is a break in the signaling is considered to be a “space.” The transition from a mark to mark is assigned a bit value of 0 or 1. An extended period of time representing a space is assigned a bit value of 1. In some situations, the timings/durations of between the marks are different depending upon the protocol specification.

Whether a given mark is given a binary encoding of 0 or 1 may also be protocol specific and in some cases an extended space is associated with a binary encoding value of 1 or 0. That is, the duration of time for a given signal high or low can be assigned differently to binary encoding.

As used herein, a “transmission” represents a plurality of signals (signaling) for a duration of time used by any given

IR remote

120 or 130 that uses a given protocol specification to communicate an IR command to an

IR device

111 or 112. The pairs of marks and extended spaces over a duration of the transmission are translated into bit values of 0 or 1 to identify the given protocol specification, verify the protocol specification, and verify the format of the payload associated with the transmission. The payload including a valid format for a command that is associated with the given protocol specification.

The verify relay device 110 includes an IR receiver 115 that captures IR transmissions provided by the IR remotes 120-130. Upon receipt of any signaling for a given transmission, the signals are saved in memory and concurrently inspected by the verifier 114 as it is being received to make a determination as to whether the signals in a transmission are associated with a valid protocol specification, which is associated with one of the supported devices 121-122. A plurality of tables 116-117 are used by the verifier 114 to verify both the protocol specification from the starting sequence and the payload (which includes an IR command) from the transmission.

Initially, the verifier 114 may retain different versions of the starting sequence of signals in the transmission. This is because some protocols may assign different binary values to the timing (measured in microseconds) and types of signals (high, low, space). Table 116 includes a column B (for Binary format used) that identifies a number value, which corresponds to that protocol's binary encoding scheme. As the starting sequence of signals of the transmission are received, the verifier 114 performs the binary encoding for the available supported protocols, such that there may be multiple binary strings for which to compare to the format that is being assembled from the starting sequence of signals. Some of the multiple binary encoded versions of the starting sequence of signals for protocols can be eliminated from consideration once a violation in one of their encoding schemes is noted. Once a match to the format column in table 116 is made with the binary encoded string, the protocol associated with that entry in table 116 is used and that protocol's binary encoding scheme is used for verifying the payload format in table 117 on the remaining signals in the transmission that follow the starting sequence.

The verifier 114 inspects a protocol identifier table 116 to determine the format of the transmission that is being simultaneously saved in memory. Table 116 is used to match the format of the starting signals of the transmission to a known IR protocol for one of the

devices

121 or 122. A matched format includes an entry that links to an index entry of the payload/command table 117; the index entry in the payload/command table 117 representing a valid expected format for the matched protocol's payload, which includes the IR command recognized by one of the

devices

121 or 122. A matched payload format in the payload/command table 117 includes an entry that includes an identifier to a specific one of IR re-transmitters 111 or 112, which is situated in close proximity to the

specific device

121 or 122 that is supposed to process the transmitted IR command in the transmission. Assuming the entire format of the transmission is verified in both tables 116 and 117, the IR transmitter 113 plays the saved transmission and the

appropriate re-transmitter

111 or 112 relays to the

appropriate device

121 or 122, which then processes the command represented in the transmission.

For example, consider RC-6 IR protocol, which defines its start sequence as a long leader pulse/symbol (represented by the S in the first entry of table 116) followed by 4 bits having a value of 1000 and followed by a trailer pulse/symbol (represented by the Tin the first entry of table 116). The starting sequence for the RC-6 protocol is defined as S1000T as shown in table 116. When the verifier 114 is able to match a transmission that is being transmitted by one of the

remotes

120 or 130 to the RC-6 protocol in table 116, the verifier 114 immediately transitions to index entry 1 of the payload/command table (using the index value provided in table 116 into table 117). Table 117 defines the RC-6 payload format at two separate 8 bit values (8BIT-8BIT in column P for Payload of table 117). Assuming the signaling following the start sequence for the transmissions matches 2 8BIT packets of information, the verifier 114 uses the IR transmitter identifier (IR T #1) located in the RC-6 payload table entry to instruct the IR transmitter 113 to play the saved transmission for IR re-transmitter 111. IR re-transmitter 111 relays the transmission to device 121. Device 121 processes the IR command embedded in the original transmission provided in the RC-6 protocol format.

It is to be noted, that if no starting sequence is matched in table 116, the transmission is not saved and is ignored, so nothing is played to any of the devices. The transmission is believed to be defective if coming from a remote that is not configured to communicate with one of the

devices

121 or 122. It is also to be noted that if a starting sequence is matched in table 116 indicating a valid supported protocol but the payload is not verified to a supported payload format in table 117, the transmission is not played to any of the devices. The transmission is believed to be corrupted in some manner.

As another example, consider the NEC IR protocol, which defines its start sequence as 9 ms of high signal (9 msH in table 116) followed by 4.5 ms of low signal (1.5 msL in table 116). A match to a transmission provided by one of the

remotes

120 or 130 to this starting sequence provides the verifier 114 with an index value of 3 into table 117 for validating the remaining portions of the transmission's payload for the NEC IR protocol. Entry 3 of table 117 indicates that the payload is expected to be comprised of 4 8 bit values (8BIT-8BIT-8BIT-8BIT in table 117). The NEC IR protocol also has additional extended verification in that the first 8 bits represent the address of the device that the transmission is directed to, the next 8 bits are the first 8 bits inverted, the next 8 bits is the command, the last 8 bits is the command bits inverted. Here, an extended column in table 117 provides a pointer to a verification function called INV. The verifier 114 passes the 32 bit string to the function identified by INV. The function returns a true or false value. True indicates the payload is validated, in which case the verifier 114 instructs the IR transmitter 113 to play the saved transmission over the re-transmitter 112 for device 122 to process the IR command included in the transmission. False indicates that the transmission can be ignored and removed from any saved memory buffer because the transmission is corrupted in some manner.

It is to be noted that a plurality of IR protocols can be supported and embodiments are not constrained to just the RC-6 and NEC protocols used as examples. Furthermore, other exception verification functions may be used beyond just an inversion verification. Each such exception function can be easily deployed via the extended column and a corresponding function to support a customized verification function.

Again, if a match to a starting sequence of an IR transmission does not match to any entry in table 116, then the entire transmission is discarded and is not replayed over either of the

re-transmitters

111 or 112. When the starting sequence is matched, the remaining payload sequence has to conform to the format defined in that matched sequence's entry in table 117. If such format for the payload does not match its entry in the table, the entire transmission is discarded from memory and is not replayed over either of the

re-transmitters

111 or 112.

In this manner, each IR transmission is verified before it is played to any

device

121 or 122 utilizing the tables 116-117 based on a supported IR protocol and its defined starting sequence and payload format. The technique allows for IR command verification for multiple different IR protocol specifications, which has heretofore been elusive in the industry. The technique also allows for custom verification based on specific requirements for each protocol's payload and/or command formats.

In an embodiment, there may be as

single re-transmitter

111 or 112 associated with 1 or multiple ones of the IR-controlled

devices

121 and 122. That is, there does not have to be a 1-1 mapping between

devices

121 and 122 and the

re-transmitters

111 and 112, there can be a one to many relationship for 1 re-transmitter 111 to

many devices

121 and 122.
